What does AllowLocation="true" do in System.Web section of Web.Config?

Question

We have a .NET 2.0 application which we normally run on IIS6, and used to run fine on IIS7, but recently after installing SP1 for Vista IIS7 seems to be choking on a line in the Web.Config file:

<system.web AllowLocation="true">

Is it safe to remove the AllowLocation attribute? What does this attribute do?

Answer 1

Having this set to true should enable any <location> sections in your web.config, so you should be fine to remove it if there's none in there.

Answer 2

From MSDN:

When set to false, the AllowLocation property indicates that the section is accessed by native-code readers. Therefore, the use of the location attribute is not allowed, because the native-code readers do not support the concept of location.

The default value is true, so you should be able to remove it with no effect on your application.
